Title: Improvements relating to gun control equipment for machine or other guns particularly mobile guns
IPC: F41A27/06
Filed: 1957-01-31
Abstract: 814,340. Training and elevating mechanisms for remote controlled ordnance. OFFICINE GALILEO, S. p. A. Jan. 31, 1957 [Feb. 4, 1956], No. 3443/57. Class 92 Relates to guns in which training and elevation are controlled remotely by means of a follow-up telereceiver comprising an electronic unit connected to the control post by cables to receive and amplify signals which control a hydro-dynamic unit effecting the training and elevational movements of the gun, the hydro-dynamic unit being operated by driving means. According to the invention instead of electric motors normally used, the driving means comprises a single thermodynamic engine, e.g. an internal combustion engine, thus eliminating the need of electrical power cables connecting the control post and gun. Pinions 10, 11 effect the training and elevation respectively and are operated by hydraulic motors 8, 9 supplied with fluid by control pumps 12, 13 driven by an I.C. engine 14 through gearing 16. The delivery of the pumps 12, 13 is controlled by electro-hydraulic governors 18, 19 which receive the control signals from amplifiers 20, the signals being transmitted from the control post over a cable 21 and the current for the amplifier being supplied through a cable 22. The gun may also be provided additionally with arrangements for local control of the training and elevation.

Filed: 1945-02-12
Abstract: 585,143. Electromagnetic relays. GENERAL ELECTRIC CO., Ltd., HALLIDAY, V. N., and HARRISON, W. J. D. Feb. 12, 1945, No. 3445. [Class 38 (v)] Energization of an electromagnet 7 causes an armature 8 to actuate contacts 9 and, by means of an arm 11, to move a member 12 out of latching engagement with an indicator 15 which therefore rotates about an axis 14 so as to appear before a window 5 and may also, if the device is suitably adjusted, bring a part 18 to bear against an extension 20 and so hold the armature closed when the magnet 7 is de-energized. The extension 20 is bendable and may, alternatively, be adjusted so that the armature is not held, but releases on de-energization. In either case the indicator 15 must be reset, which may be effected by a tool inserted by hand to engage a bar 21. A number of relays may be mounted side by side with a common resetting bar.

Title: Peristaltic pumps
IPC: C08G75/00
Filed: 1977-01-28
Abstract: 1528893 Peristaltic fluid-machines J W GERRITSEN 28 Jan 1977 [24 Feb 1976] 03575/77 Heading F1U [Also in Division F2] A pump has a pumping tube 34 wherein layers of reinforcing "threads" e.g. steel wires, 52, 53 are wound helically in opposite directions and cross each other at an angle relative to the tube's axis 54 greater than the "equilibrium angle", which is 54 degrees and said to bring about minimal elongation and circumferential enlargement of the tube by the working fluid. The cross-angle may be 63 degrees so that the consequent tendency to elongation matches the tendency to shortening of the portion of the tube between the downstream end of the tube and an adjacent "compression member" e.g. a roller 10 compressing the tube against a track 35 and travelling around the axis of a drive shaft 20 towards the said end. The rollers may be moveable about pivots 27 by adjusting bolts 32. To reduce friction the compression members and the tube may be immersed in glycerine.

IPC: F21V21/26
Filed: 1935-02-05
Abstract: 449,488. Ball joints. NIELSEN, K. A. N., 30, Jyllandsvej, Frederiksberg, Copenhagen. Feb. 5, 1935, No. 3748. [Class 65 (ii)] [See also Group XI] In a ball joint, particularly for supporting electric lamps, of the kind wherein a metal sleeve 10 is placed between the ball 7 and its socket 6, the wall of the sleeve is so thin and the metal of which it is made, e.g. copper, so yielding that the sleeve is forced to embrace the ball closely when it is pressed down in the socket. In the form shown the sleeve is pressed down by a spring 14, bearing against the base 3 to which the socket is attached, through the intermediary of a rubber ring 12 between two washers. The sleeve and the ball are preferably made of metals having such mutual friction that turning of the ball draws the sleeve tightly against it, so that it is held in any position of adjustment. In the form shown, the sleeve is in one piece, but in a modification it is divided longitudinally into a number of strips, which are pressed outwards against the wall of the socket by a spring ring.

Title: Improvements in machines for the manufacture of cellular networks
IPC: B27D1/06
Filed: 1954-02-09
Abstract: 746,117. Honeycomb paper; laminated materials. DALO, M. Feb. 9, 1954 [Feb. 9, 1953], No. 3778/54. Classes 96 and 140. [Also in Group XXIII] A machine for making cellular or honeycomb networks from laminµ 3 of thin wood, cardboard or like material fed from reels 4 comprises an adhesive-applying device 5, a comb 6 for preliminarily shaping the laminµ, caps 8 and heated tubes 11 which are consecutively raised to separate and bend the laminµ, jacks 15 for applying lateral pressure to unite the network and belts 17 for removing the continuous network lengths. The comb 6 comprises a number of blades 18 on a plate 19 rocked about an axis 20 and swellings 21 at the ends of the blades roughly shape the laminae to allow easier penetration of the caps 8. The caps 8, which are resilient and longitudinally divided to provide two wings 24, are raised by a frame 12 and jacks 13 to penetrate between the laminµ and then the tubes 11, which have pointed ends and resilient tails and are heated by internal electric resistances, are raised by a frame 9 and jacks 10 to bend the laminae. Finally, the jacks 15 compress the network laterally to such an extent that the thickness of the laminµ at the points of adhesion is reduced by from 5 to 30 per cent. The caps 8 and tubes 11 are guided by one or more gratings 14 which have transverse elements 27 of corrugated resilient steel with apertures 29 in which lugs 30 of longitudinal elements 28 are fitted and under the pressure of the jacks the transverse elements deform in concertina fashion while the longitudinal elements slide on bars 32. The resilience of the caps 8 and tubes 11 allows them to follow the deformation of the grating but, in a modification, the caps slide on guides at their lower ends and the tubes are attached by resilient plates to the frame 9.
Patent GB-575189-A (GB)
Title: Improvements in and relating to automatic arc welding apparatus
IPC: B23K9/12
Filed: 1944-03-02
Abstract: 575,189. Uniting by fusion. ROWEN, J. N., and WHITELEY-READ ENGINEERS, Ltd. March 2, 1944, No. 3894. [Class 83 (iv)] In an automatic arc-welding machine in which a number of independent flux-coated electrodes are fed to the work sequentially and the electrode in use is automatically welded to the next electrode to be used, the electrodes are fed by a succession of grippers movable one after another along a feed path, each gripper closing on the end of an electrode as it enters said path to carry the electrode along in end contact with a preceding electrode and being opened to release the electrode about the time it leaves said path, at least two electrodes in series being incorporated in the electric circuit. Flux-coated electrodes E<1>, E<2>, E<3> may be fed sequentially from a hopper by spring-opened pivoted jaws A<1>, A<2>, A<3> connected to but insulated from a chain C driven at a variable rate depending on the rate of consumption of the electrode. The jaws engage fixed and spring-mounted copper contact strips D, D<1> connected to one terminal of the electric circuit, the upper parts being splayed out so that as the jaws descend they grip the part 9 of the upper end of the electrode from which the flux has been removed. At or near each end of the strips are a pair of pivoted arms G which pass through slots in the strips and are normally extended by springs 6 in the position shown so as to act as electrode guides. The lower end of the electrode E<2> is in contact.with the upper end of the partly consumed electrode E<1> which is gripped by the jaws A<2>, passes through the guide tube 8, and has its lower end in arcing relation with the work, and the upper end of-electrode E<2> is in contact with the electrode E<3> which has been automatically fed by gravity &c. from the hopper. While the jaws A<2> are in contact with the strips D, D<1> they supply current to the electrode E<1> direct, but when the jaws leave the strips and pass between insulating blocks F at the lower ends thereof, current to electrode E<1> is supplied through jaws A<1> and electrode E<2>, the bad electrical contact between the adjacent ends of the electrodes E<1>, E<2> causing arcs therebetween so that they are united together by fusion by the time the jaws A<2> have left the blocks and have opened so as to release them from the electrode. As the jaws move downwards they force open the arms G in turn. In a modification, two chains may be provided, geared together and arranged one on each side of the strips D, D<1> and the pivoted jaws are replaced by single jaws on one chain which co-operate with similar jaws on the other chain to grip the electrodes.

[Class 55(i)] Wood, coal or shale is distilled in a retort to which an excess of heat is supplied by an enclosing combustion-chamber, the temperature of the charge being controlled by passing a heat-absorbing medium through ducts arranged in or adjacent to the retort walls, the ducts being so arranged that a greater degree of heat extraction is effected at a zone which would otherwise become overheated, than at another part of the retort which is not liable to overheating. The heat-absorbing medium may be water or steam and the retort may be of rectangular or circular section. As shown 'in Figs. 1, 2, the retort 2 is rectangular in section and divides the outer chamber into two combustion spaces which are fed by shoots and valves 9, 10, and are provided with rotary discharge means 4. The fuel may be coke discharged from the retort 2 by a worm conveyer 6, and delivered to the shoots 9 by an elevator 8. The retort is fed from a hopper 3, past valves 5 which prevent the escape of gas, and descent of the charge is maintained by rotary means 4a. Ash is removed through the water seal 11, 11a and gas is withdrawn through a pipe 13a. Cooling pipes 12a are arranged adjacent to the retort walls, and extend to different levels so that the cooling-effect is varied as necessary. Cooling pipes 12b are arranged, as described in Specification 641,541, in the fuel bed to maintain the fuel near but below the sintering temperature. Air for combustion is supplied at 21 and combustion products escape at 22. A number of retorts of downwardly divergent tapering section may be arranged side by side in one large combustion chamber, the gas being withdrawn from the top of one retort and from about the middle of another retort. In a modification, the retort is enclosed in a chamber which is fired at the bottom by gas-burners, and the cooling pipe, or pipes, is coiled around the retort, the coils being spaced closely at the bottom of the retort in the vicinity of the burners. According to the Specification as open to inspection under Sect. 91, the wall of the retort may be composed of tubes or of tubes spaced by distance pieces- This subjectmatter does not appear in the Specification as accepted.

Abstract: 1,100,123. Vibration damping arrangements. NATIONAL RESEARCH DEVELOPMENT CORPORATION. 17 March, 1966 [29 Jan., 1965], No. 4175/65. Heading F2S. In a method of protecting equipment, such as electronic and similar delicate apparatus, from heavy shocks which may be experienced on ships' decks, the equipment is connected by anti-vibration spring elements and dampers as shown to a platform which is normally held rigid, e.g. to the deck, by shock-absorbing and stiff spring elements. Each shock-absorbing and spring element comprises a rod, Fig. 2, not shown, which is hinged to the platform and which has a pair of flanges, a pair of split washers, which frictionally engage within a cylinder pivoted to the deck, being normally urged by the outer of a pair of concentric springs into engagement with the rod flanges. An inner spring bears against the lower washer, but passes through the opening in the upper washer to bear against the upper flange so that both springs, or only the central spring are, or is, compressed respectively during relative converging or diverging movements of the platform and the deck. A satisfactory mounting, Fig. 3, not shown, comprises a tripod arrangement of shock-absorbers and spring elements at each corner of the platform.
